Install the new ozonator
using the enclosed hardware (instructions are included)

My spa is ozone ready--I want to add an ozonator.

Electrical Requirements:

All ozonators are supplied
with power cords and are hooked to the equipment control box via a supplied
cord end, or they are hard wired directly into the control box. Look on the
side of your control box where everything plugs in, if you see an empty slot
that will except a (3) prong plug then most likely this is the receptacle for
the ozonator. Please look at the selection of
cord end to select the proper pattern.

Plumbing
Requirements:

If your spa is 'ozone
ready' then one of two things are apparent:

You have located
and identified a clear tube (approximately 3/8") that is just hanging in
the equipment area with either a knot or plug at the end that is not attached
to anything.

You have located
and identified a section of 3/4" ID flex hose spliced into a rigid water
line, which leads to a special ozone jet in the spa shell.

for these instructions

(1) If this is the case then the first thing you will want to do is remove
the plug/knot at the end of the tube, then start the pump on the low speed filter/heat
cycle. Once this is done, you'll want take the end of the tube and check for
a slight "suction" or "draw". This can be achieved a couple of ways; you can
either put it on your tongue and check for suction, or you can find something
very small and light to see if it gets sucked into the tube. If you are getting
the suction mentioned above, then the next step is to identify the
cord end that matches the receptacle on your control box, then purchase
the
ozonator that matches the
cord end you chose. Spa Parts Ltd. recommends
using a
DELZONE
unit. If the tube is not drawing a suction, then please follow the instructions
below. (In the yellow box)

Once you receive the ozonator,
find a suitable mounting location that will keep it up and out of any water.
The next step is VERY IMPORTANT, failure to do so will jeopardize the new ozonator
and void the warranty. You will want to create a "loop" (Hartford Loop) in the
tubing and install it as high as possible under the spa to keep water from backing
up into the ozonator as shown below.

Water should never be allowed to enter the ozonator! If the existing tubing
in your spa is not long enough to create this loop you can purchase a coupling,
from any home center to join your tubing to the tubing that comes with ozonator.

An in-line check valve is also included in every ozone kit and should be used.

Please install it per the instructions, making sure that it is installed in
a manner the will allow the ozone to be "drawn" through the tube into the spa.

You can now plug the cord into it's power source, depending on the manufacturer
of the ozonator you should have an indication of weather it is working or not
by either a site glass or a "blue glow" coming from the manifold. It is best
to check this at night. Now turn on the filter/heater cycle and take a look
in the spa, there should be one jet that is spitting small bubbles. It is these
bubbles that the ozone uses as a vehicle to enter the spa water.

(2)
If you have
located the flexible tube mentioned, then your next step is to order the in-line
injector
P/N 684K-MAZZEI and ozonator, Spa Parts Ltd. recommends using a
DELZONE
unit.Make sure
you order the proper ozonator with the correct
cord end that will match the receptacle on your control box.

Once you
receive the injector, you will simply cut out a piece of the flex tube in order
to install the injector. (See below) Make sure to install
the injector with the arrow pointing in the same direction that the water is
flowing.

When Installing the ozonator, find a suitable mounting location that will
keep it up and out of any water. Connect the supplied tubing from the injector
barb to the ozonator barb. The next step is VERY IMPORTANT, failure to do so
will jeopardize the new ozonator and void the warranty. You will want to create
a "loop" (Hartford Loop) in the tubing and install it as high as possible under
the spa to keep water from backing up into the ozonator as shown in (Figure
1) above. Water should never be allowed to enter the ozonator. An in-line check
valve is also included in every ozone kit and should be used. Please install
it per the supplied instructions, making sure that it is installed in a manner
the will allow the ozone to be "drawn" through the tube into the spa. You can
now plug the cord into it's power source, depending on the manufacturer of the
ozonator you should have an indication of weather it is working or not by either
a site glass or a "blue glow" coming from the manifold. It is best to check
this at night. Now turn on the filter/heater cycle and take a look in the spa,
there should be one jet that is spitting small bubbles. It is these bubbles
that the ozone uses as a vehicle to enter the spa water.

All ozonators are supplied
with power cords and are hooked to the equipment control box via a supplied cord
end, or they are hard wired directly into the control box. Look on the side of your
control box where everything plugs in, if you see an empty slot that will except
a (3) prong plug then most likely this is the receptacle for the ozonator. Please
look at the selection of
cord end to select the proper pattern. If you do not see a receptacle then
you will need to hard wire the ozonator cord into the control box. The electrical
cord should be wired to the pump relay or switch so that the ozonator comes on only
when the pump is on; for 2-speed pumps, the ozonator should be wired to the low-speed
pump relay (NOTE: The ozonator should only operate when the low speed pump
is running).

The Concept:

This installation
will require taping into the air line via a barbed fitting (see Figure 2 below).
This line is plumbed in series from jet to jet and eventually ties into an air control
(you may have more then one) that is mounted on top of the spa. While the jets are
running you'll notice that if the air control is closed it will not allow air to
mix with the water coming out of the jets in the spa. However if you open it, the
jets increase in power due to the fact that air being pulled in from the air control
is now mixing with the water coming out of the jets. This action is called "Venturi".
This installation is going to use the same concept; except, instead of the "mixing
air" or pulling air from the air control, it will pull air from the ozonator. Now
the air that mixes with the water will have ozone in it and sanitize your spa.

My spa is not ozone ready-- I want to install one.

If your spa has more then one air control, you'll want to "tie" into the one that produces the most air when it is opened. With the pump running on low speed, turn off both air controls, open one at a time observing the air mixture that is coming out of the jets. The air control that allows the most air to mix with the water coming out of the lowest jet; if possible, is the one you will want to plumb into.

»If you have more
than one air Venturi line, select the one with the best suction,
connected to the lowest spa jet if possible (see plumbing requirements
above)

»Cut the PVC pipe
(usually 1") and install a tee, in the side port of the tee you'll need
to install a barbed fitting (found at any Home Center) that will
except the 3/8" tubing included in the ozone kit. (Fig 2)

»Connect a 6"
piece of tubing to the barbed fitting, at the other end install the
provided check valve. Once this is done, blow into the check valve, the
air should flow freely towards the tee, if you feel back pressure when
doing this, you have the check valve installed backwards.

»Attach a 5-6 foot
length of flexible tubing to the check valve and route the hose so that
at some point it passes above the water level of the spa. You may need
to tie the hose up to keep it in place. This will help insure that no
water backs up into the ozonator. (Fig 2).

»Before attaching
it to the ozonator you should test the line to make sure that it will
have an adequate amount of suction to draw in the ozone from the
generator as well as making sure water does not back up into the line.
You'll need to fill the spa up with water, shut the air control valve
off, and start the low speed pump. You should see bubbles mixing with
one or more jets. Placing your thumb over the tube should make them
disappear. If this is the case, then you have successfully installed the
plumbing.

»Connect the final
end of tubing to the ozonator barb and plug in the ozonator

»Systems are
either 120 or 220 VAC, 50/60 HZ. For hard wire installation wire ozone
generator systems to the low speed side of the circulation pump switch
or timer. Follow your local electrical code for grounding and
installation procedures for spa equipment.

»FINAL
NOTE: The mentioned tee can be installed vertically (as shown)
or horizontally anywhere in the air control line. However, the closer to
a jet you can get the better.

Systems are either 120 or 220 VAC, 50/60 HZ. Wire ozone generator systems to the low speed side of the circulation pump switch or timer. Follow your local electrical code for grounding and installation procedures for spa equipment.

»You will need to
purchase an
ozone injector for this installation. You'll also need to determine
weather the line you are installing the injector in is 1.5" or 2". Use P/N
OZINJ1 or
OZINJ2.

»The injector is
installed after the filter/heater make sure that the "flow" arrow is
pointing towards the spa.

»Connect a 6" piece of
tubing to the barbed fitting, at the other end install the provided check
valve. Once this is done, blow into the check valve, the air should flow
freely towards the injector, if you feel back pressure when doing this, you
have it check valve installed backwards.

» Once this is done push the provided tubing onto the injector barb.

Installing a self contained ozonator-(no plumbing required

Electrical Requirements:

»Ozone can be
delivered continuously, up to 24 hours per day, when wired independently of
the spa pump by simply plugging it in into a regular (nema) receptacle. Or
you can wire to the low side pump circuit in the control box, for controlled
operation.

Installation
Requirements:

The self contained ozone
generator can be mounted anywhere in the equipment area, or it can be mounted to
an outside wall. If you are mounting it in the equipment area, make sure the
check valve is installed and a "Hartford Loop" (Fig 1) is installed to prevent
water from backing up into the ozonator. If the unit is going to be mounted on
an outside wall, place the unit above water level, this will prevent water from
siphoning into the ozonator.

»Connect a 6" piece of
tubing to the barbed fitting, at the other end install the provided check
valve. Once this is done, blow into the check valve, the air should flow
freely towards the tee, if you feel back pressure when doing this, you have
the check valve installed backwards.

»Attach a 5-6 foot
length of flexible tubing to the check valve and route the hose so that at
some point it passes above the water level of the spa. You may need to tie
the hose up to keep it in place. This will help insure that no water backs
up into the ozonator.(Fig 1)

For temporary or simple installation, slide the ozonator tubing onto the barbed wall fitting and let it hang over the edge into the spa water.

Ozone Troubleshooting Guide

When your spa is in it's
"on" cycle a suction of air is being pulled through the tubing from the ozonator
to the return line. As the air passes by the UV bulb or chip, the oxygen in the
air is converted to ozone. This ozonated air is introduced to the water via an
action known as "Venturi". When your spa is in it's "off" cycle water tends to
flow back in the tubing towards the ozonator. Therefore, installing the provided
check valve and a "Hartford Loop" (see illustrations above) will help prevent
this from happening.

Ozone is introduced into
the water via the low speed (filter) mode. It is recommended that it runs on a
24 hour cycle, although, it can operate on the timer mode as well. You may have
to keep a chlorine or bromine reserve when operating in this mode. The 24 hour
cycle mode will not only cut back your chlorine or bromine use, but may replace
it all together. It is recommended you use a
Non-Chlorine Shock or a Mineral Cartridge such as
Nature2 (not bromine compatible) or
The Frog (bromine compatible). These three combined will keep your water
sanitized and crystal clear.
